The Wave form of a Longitudinal Reflected Wave from a Thin High-Speed LayerThe wave forms for longitudinal waves reflected from a thin but uniform layer have been studied theoretically , on models , and in actual media , Recently, theoretical studies have appeared which develop the wave forms for waves reflected from a periodic sequence of thin layers .Robust 发表于 2025-3-25 10:07:11
Head Waves from Thin Layers (From Field Data)The study of seismic waves from thin layers is of considerable practical interest, inasmuch as thin layers with distributed elastic properties seems to be the normal mode of occurrence for actual media made up of sedimentary rocks.泥沼 发表于 2025-3-25 14:25:49
Introductionst commonly used representation for the Earth has been a set of thick layers, each characterized by a single value for the propagation speed of seismic waves. During the last several years, more complicated representations in the form of thin layers with vertical velocity gradients, as well as homogeneous thin layers have been considered.SSRIS 发表于 2025-3-25 18:51:00

Method for Recording Direct Longitudinal Waves at the Surface and Within a Mediumhe nature of propagation of seismic waves in such media. The wave forms and arrival times of waves recorded both at the surface and at interior points in the medium are used in obtaining these data .Offbeat 发表于 2025-3-26 03:30:29
